Data Link 2 - They are in the same Frame Which OSI layer is a Switch at? Data Link 2 Which OSI layer is a WAP (Wireless Access Point) at? Which OSI layer is a router at TCP protocol is on what OSI layer OSI layer 1 Network (3) Transport (4) Physical Layer (Cable, Hubs, Repeaters) OSI layer 2 Data Link 2 Data Link Layer (Frame, Switch, PPP, Ethernet) OSI layer 3 OSI layer 4 OSI Layer 5 OSI layer 6 OSI layer 7 Network Layer (Moves packets, IP) Transport Layer (TCP, end to end connection) Session Layer (API, Sockets, Synch and send to port) Presentation layer (Syntax and encryption layer, SSL, SSH, JPEG) Application layer (end user layer, http, applications) Network Typology point to point Two devices connect directly Network Typology bus All devices connect to a central main line Network Typology Ring Network Typology Star Network Typology Tree connected with each other Network Typology Mesh Network Typology Hybrid All devices have two connections and form an endless ring All devices connect to a central point Multiple devices connect together (on a switch) and then the switches are All devices connect directly to each other Multiple Network Typology within the network Cloud - where do I manage the OS Iaas or Paas? What do I manage on Paas (2) Iaas Application and Data Name the 3 CIA triades Integrity, Availability and Confidentiality What is the CIA Triade Integrity? What is the CIA Triade Availability? Detects alteration in storage, transit and process Ensure Authorized Access, Performance and Backup Keeping unauthorized users out is not in this triade. What is the CIA Triade Confidentiality? access in storage, transit and process Protect from unauthorized access and use, protecting data 100m long Cat 5 cable supports speeds up to 100m long Cat 5e cable supports speeds up to 100 Mb/s 1000 Mb/s or 1 Gb/s 100m long Cat 6 cable supports speeds up to 10 Gb/s 100m long Cat 6a cable supports speeds up to Does a firewall provide two way protection? Firewall that only checks the address label On what OSI level is a Packet Filter operating Network (checks source and destination IP) What is a circuit level gateway 10 Gb/s Yes, it protects ingress and egress data Packet Filter Transport (checks TCP/UDP prot numbers) and A firewall that conceals the true identity of the protected network (hides IP) on the transport (4) layer What does state in stateful mean? It refers to the connection state between two computers Why do we need the 5th layer on a Stateful Inspection In this connection, the firewall is creating temporary rules per session to permit communication (TCP) back to the sender. What is a stateful inspection It reduces the amount of firewall rules. Firewall vendors implemented a feature that only needs one rule to allow the initial communication. How do we protect the application level with a firewall 7 firewall Can a packet filter firewall scan the packet content? What is a IDS With a proxy server, Middle man or Layer No, a layer 7 or proxy is needed Intrusion Detection system. A system for detecting attempting intrusion. Related to intrusion prevention systems (IPS) that block suspected attacks What is IPS Intrusion Prevention System that can block traffic if a malicious anomaly is detected
